Extremely precise measurements of the muon magnetic dipole moment two decades ago revealed a tantalizing hint of an anomalous excess at the sub-ppm level over Standard Model predictions. This ~3.5 sigma discrepancy has been widely cited due to the anomaly's potential for constraining many natural extensions to the Standard Model. A new experiment at the Fermi National Accelerator Laboratory will be able to refine this measurement by a factor of four over the next few years by measuring the spin precession of 3.1 GeV muons trapped in a precisely tuned magnetic field. This talk offers an update on the early stages of the experiment and our expectations for accumulating the required statistics.
